Anti-immigrant activist William Gheen this month said that the increase of undocumented immigrants crossing the border into the U.S. is more dangerous than an al Qaeda attack.

In an interview on the Tea Party News Network, host Larry Altman asked Gheen how many undocumented immigrants might be “affiliated with Al Qaeda.”

Gheen, president of the Americans for Legal Immigration PAC, which has been designated a hate group by the Southern Poverty Law Center, launched into an answer about how immigrants will destroy America.

“Well, what the illegals that are coming — and especially the ones that are coming from China — are going to do to America are much more powerful and lasting impacts than anything Al Qaeda could blow up, short of a nuclear detonation,” he began.

He then said that undocumented immigrants will ruin the lives of Americans who have lived in the country for years. They could even keep kids from attending their top choice university, he warned.

“And how do you put a price tag on a family, let’s say that’s been in the United States for 300 years, and four or five different members of that family have gone off to World War II and Korea and maybe World War I to fight for the American way of life, and then finally they get to their grandson that’s alive in the year 2020 who doesn’t get to go to the college of their choice because invaders have been brought in the country and put in those seats ahead of him,” Gheen said.

“That child’s life, that negatively impacts that child’s ability to self-actualize, to be all they can be, impacted because the future has been stolen by this usurpation, this treason, this treachery from the highest levels of our own government right here in the United States of America,” he continued.

Gheen concluded by arguing that undocumented immigrants are an incredibly dangerous “weapon.”

“Once they get enough people in here to get the boat really sinking, and then they get the borders destroyed and they start taking up all the guns and we’ve got wave after wave of future illegal immigrants just pouring in, pouring in, pouring in, the existing stock of Americans are going to be so politically and economically buried under this wave, that it’s a weapon from which we can never recover,” he said.
